Argentina forward Lavezzi added two more goals before half-time, but Montenegro defender Basa pulled one back for Lille after the break.

Any hopes of a comeback were dashed when Sebastien Corchia gave away a penalty - converted by Cavani - and was sent off.

Lavezzi rounded off the scoring with his third goal 13 minutes from time as PSG notched their fifth successive league win.

In the pick of the day's other Ligue 1 games, 18-year-old Francois Kamano scored twice as Bastia came from behind to beat relegation rivals Evian 2-1. They are now three points clear of 18th-placed Evian.
